Answer:
The answer is 4000 m³
Step-by-step explanation:
Given;
- Depth of river (h) = 3m
- Width of river (b) = 40m
- Rate of water flow = 2 km/hour
To Find;
- We have to find out how much water will fall into the sea in a minute.
Now,
Rate of water flow = 2 km/hour
= 2000m/60min
= 100 m per min
Now, Volume of water flowed in 1 min,
= (100/3) × 40 × 3 = 4000m³
Thus, 4000 m³ of water will fall into the sea in a minute.
